Overview
The 1P1G66QDBVRQ1 is a single bilateral analog switch from Texas Instruments, designed for automotive applications. It features a 1:1 SPST configuration with a maximum on-resistance of 25 Ohms. The device operates within a supply voltage range of 1.65 V to 5.5 V and supports a continuous switch current of 100 mA. Key performance metrics include a maximum on-time of 7.2 ns and an off-time of 6.9 ns. It is housed in a SC70-5 package and meets AEC-Q100 qualification standards.
Feature Summary
- Single-channel bilateral analog switching capability
- Automotive-grade reliability with AEC-Q100 qualification
- Low on-resistance for efficient signal transmission
- Fast switching speeds suitable for high-frequency applications
Applications
- Automotive infotainment systems
- Sensor signal routing in vehicle networks
- Data acquisition systems requiring low impedance switching
- Portable electronic devices with strict power constraints
Procurement Notes
Verify the specific suffix 'QDBVRQ1' matches the required automotive grade and packaging format. Confirm that the SC70-5 footprint aligns with your PCB design guidelines. Ensure the supplier provides documentation confirming AEC-Q100 compliance for quality assurance purposes before finalizing orders.
Selection Notes
Select this component when a single-pole single-throw switch is needed with low on-resistance and fast transition times. Consider the 1.65 V to 5.5 V operating range for compatibility with various logic levels. The SC70-5 package is ideal for space-constrained designs requiring surface-mount installation.
Part Context
This part belongs to the SN74LVC1G66 family of single analog switches. It is specifically tailored for automotive environments, offering robust performance under varying temperature conditions. The device complements other logic and interface components in complex automotive electronic architectures.
Replacement Considerations
Direct substitutes may include non-automotive grade variants like SN74LVC1G66 if automotive certification is not required. Verify pinout compatibility and electrical specifications such as on-resistance and switching speed when considering alternative manufacturers or series.
